Zhipu AI released the open weights of GLM-5.2 on HuggingFace under an MIT license around June 16, 2026. The model is built on a 753B MoE architecture with a 1-million-token context window, coding-first positioning, and a dual thinking-effort system with no regional restrictions, hosted at zai-org/GLM-5.2.

Why it matters

Unrestricted MIT open-source release of a 753B frontier-tier MoE model with 1M context, directly competitive with leading closed models for enterprise long-horizon agentic coding globally.

Importance: 4/5
